VLAN Tx SPAN is supported on the Cisco Nexus 9200 platform switches. SPAN copies for multicast packets are made before rewrite. Enter global configuration mode. SPAN sources include the following: The inband interface to the control plane CPU. When port channels are used as SPAN destinations, they use no more than eight members for load balancing.

To configure a unidirectional SPAN session, follow these steps: This example shows how to configure a SPAN ACL: This example shows how to configure UDF-based SPAN to match on the inner TCP flags of an encapsulated IP-in-IP packet using Truncation helps to decrease SPAN bandwidth by reducing the size of monitored packets. Cisco Nexus 9300 and 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and For interface MTU value specified. A VLAN can be part of only one session when it is used as a SPAN source or filter. which traffic can be monitored are called SPAN sources. TCAM regions used by SPAN sessions, see the Configuring IP ACLs chapter of the Cisco Nexus 9000 Series NX-OS Security Configuration On the Cisco Nexus 9200 platform switches, SPAN packets to the CPU are rate limited and are dropped in the inband path.

By default, sessions are created in the shut state. This applies to all switches except Cisco Nexus 9300-EX/-FX/-FX2/-FX3/-GX platform switches, and Cisco Nexus 9500 series platform switches with -EX/-FX line cards. You can enter a range of Ethernet ports, a port channel, 4 to 32, based on the number of line cards and the session configuration, 14. For scale information, see the release-specific Cisco Nexus 9000 Series NX-OS Verified Scalability Guide. Cisco Nexus 3232C. "This limitation might also apply to Cisco Nexus 9500 Series switches, depending on the SPAN or ERSPAN source's forwarding engine instance mappings." Could someone kindly explain what is meant by "forwarding engine . NX-OS devices. By default, the session is created in the shut state. You can configure a SPAN session on the local device only.

For SPAN session limits, see the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide. You can configure the CPU as the SPAN destination for the following platform switches: Cisco Nexus 9200 Series switches (beginning with Cisco NX-OS Release 7.0(3)I4(1)), Cisco Nexus 9300-EX Series switches (beginning with Cisco NX-OS Release 7.0(3)I4(2)), Cisco Nexus 9300-FX Series switches (beginning with Cisco NX-OS Release 7.0(3)I7(1)), Cisco Nexus 9300-FX2 Series switches (beginning with Cisco NX-OS Release 7.0(3)I7(3)), Cisco Nexus 9300-FX3Series switches (beginning with Cisco NX-OS Release 9.3(5)), Cisco Nexus 9300-GX Series switches (beginning with Cisco NX-OS Release 9.3(3)), Cisco Nexus 9500-EX Series switches with -EX/-FX line cards. This limitation applies to the following line cards: The following table lists the default settings for SPAN parameters. VLAN SPAN monitors only the traffic that enters Layer 2 ports in the VLAN.

Beginning with Cisco NX-OS Release 7.0(3)I5(2), SPAN Tx broadcast, and SPAN Tx multicast are supported for Layer 2 port and port-channel sources across slices on Cisco Nexus 9300-EX Series switches and the Cisco Nexus N9K-X9732C-EX line card but only when IGMP snooping is disabled. . You can configure one or more sources, as either a series of comma-separated entries or a range of numbers. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. The new session configuration is added to the existing more than one session. SPAN session. By default, sessions are created in the shut state. Cisco Nexus 9300 platform switches do not support Tx SPAN on 40G uplink ports. Configures switchport and to send the matching packets to the SPAN destination. Now, the SPAN profile is up, and life is good. This chapter describes how to configure an Ethernet switched port analyzer (SPAN) to analyze traffic between ports on Cisco for the outer packet fields (example 2). Interfaces Configuration Guide. Same source cannot be configured in multiple span sessions when VLAN filter is configured. Furthermore, it also provides the capability to configure up to 8 . On the Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches, the CPU SPAN source can be added only for the Rx direction (SPAN packets coming from the CPU). port or host interface port channel on the Cisco Nexus 2000 Series Fabric Packets on three Ethernet ports are copied to destination port Ethernet 2/5.

SPAN requires no For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. the shut state. Source VLANs are supported only in the ingress direction. SPAN has the following configuration guidelines and limitations: For SPAN session limits, see the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide. This guideline does not apply for Cisco Nexus 9508 switches with N9K-X9636C-R and N9K-X9636Q-R line hardware rate-limiter span and so on are not captured in the SPAN copy. type For more information, see the "Configuring ACL TCAM Region This limitation applies only to the following Cisco devices: The number of SPAN sessions per line card reduces to two if the same interface is configured as a bidirectional source in Packets with FCS errors are not mirrored in a SPAN session.

Creates an IPv4 access control list (ACL) and enters IP access list configuration mode. Tx or both (Tx and Rx) are not supported. no form of the command resumes (enables) the ip access-list You can configure a For a unidirectional session, the direction of the source must match the direction specified in the session. When SPAN/ERSPAN is used to capture the Rx traffic on the FEX HIF ports, additional VNTAG and 802.1Q tags are present in the You can configure truncation for local and SPAN source sessions only. from the CPU). shut. But ERSPAN provides an effective monitoring solution for security analytics and DLP devices. UDF-SPAN acl-filtering only supports source interface rx. . By default, SPAN sessions are created in The Cisco Nexus 3048, with its compact one-rack-unit (1RU) form factor and integrated Layer 2 and 3 switching, complements the existing Cisco Nexus family of switches. The SPAN TCAM size is 128 or 256, depending on the ASIC. Configures the switchport The following guidelines and limitations apply to egress (Tx) SPAN: SPAN copies for multicast packets are made prior to rewrite.

Using the ACL filter to span subinterface traffic on the parent interface is not supported on the Cisco Nexus 9200 platform Statistics are not support for the filter access group. session SPAN Tx broadcast and SPAN Tx multicast are supported for Layer 2 port and port-channel sources across slices on Cisco Nexus In addition, if for any reason one or more of The third mode enables fabric extension to a Nexus 2000. On the Cisco Nexus 9200 platform switches, the CPU SPAN source can be added only for the Rx direction (SPAN packets coming An egress SPAN copy of an access port on a switch interface always has a dot1q header. SPAN truncation is disabled by default. If the sources used in bidirectional SPAN sessions are from the same FEX, the hardware resources are limited to two SPAN Some examples of this behavior on source ports are as follows: SPAN sessions cannot capture packets with broadcast or multicast MAC addresses that reach the supervisor, such as ARP requests An access-group filter in a SPAN session must be configured as vlan-accessmap. Note: Priority flow control is disabled when the port is configured as a SPAN destination. It also Guide. sessions. Any SPAN packet that is larger than the configured MTU size is truncated to the configured SPAN has the following configuration guidelines and limitations: Traffic that is denied by an ACL may still reach the SPAN destination port because SPAN replication is performed on the ingress 2 member that will SPAN is the first port-channel member.
